I recently took my new Klim Wolverine bag on a vacation to Savannah, Georgia. While the bag does meet the size requirements for Delta Airlines, they offered free baggage check so I took advantage of that. Needless to say, the baggage handlers at the airlines are not gentle with anything. The Klim Wolverine bag held up great to their abuse! The bag had enough room to carry everything I needed for my 10 day vacation, lots of pockets and compartments to nicely sort stuff out, nice telescoping handles and wheels so it's easy to go through the airport with, very sturdy zippers. I would recommend this bag to anyone looking to do some travel.
